Lpete-
There are 4 positions on my switch. Of course the Lowest would seem to be OFF.
But it says LO

James, 12 v on the gray wire and 12 v to the fan *is* high speed. Are you saying that's how it is in position 3, not "hi"?

I'll go double check that now.
In Med Hi (3rd of the 4 positions including LO/Off) I have power on RED GREY and BLACK ORANGE)
In Med Lo ( 2nd of 4 positions including LO/Off) I have power on RED, GREY
THese positions run the fan as they should.

How would I test that as you described?

grounding the brown wire at the relay should energize the relay and turn the blower on high. If it doesn't, the relay must be bad. In any case, connecting B+ and ground to the relay terminals with the gray and brown wires should make the relay click.

Would I try to ground the brown wire? with the Key on?

I went out and accidently jumped the Red and Brown with the Paper Clip.. YOWWWW
Burned my hand! Dont DO THAT!
